Not having weapons around hospital, so not injured (8)
I believe the answer is:
unharmed
'not injured' is the definition.
(I've seen this before)
'not having weapons around hospital' is the wordplay.
'not' becomes 'un' (I've seen this in other clues).
'having weapons' becomes 'armed' (I've seen this before).
'around' indicates putting letters inside.
'hospital' becomes 'h'.
'un'+'armed'='unarmed'
'unarmed' placed around 'h' is 'UNHARMED'.
'so' acts as a link.
(Other definitions for unharmed that I've seen before include "not wounded" , "Not injured or damaged" .)
